質問 2：
A customer has a number of non-IBM storage arrays, which are capable of provisioning using only traditional RAID volumes. Over-allocation of storage is an issue on some arrays and not on others. In order to balance storage use across the arrays, the customer wishes to virtualize the environment.
Which advantage would IBM SAN Volume Controller provide over EMC VPLEX?
A. SAN Volume Controller can provide thin provisioned volumes to reduce capacity if the array supports thin provisioning.
B. SAN Volume Controller can provide Real-time Compression to reduce capacity if the array supports compression.
C. SAN Volume Controller can provide block-level deduplication to reduce capacity regardless of array capability.
D. SAN Volume Controller can provide thin provisioned volumes to reduce capacity regardless of array capability.
正解：D
質問 3：
